Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, determining the optimal wireless base station for connection based on communication history is challenging due to the degradation of connection probability to small cells, especially when area blocks are either too large or too small, leading to inaccurate base station selection and increased demand for location accuracy and time.
Innovation Solution
A wireless terminal and method that accumulate location information and communication history with multiple wireless base stations, derive the optimal connection base station using location information and communication history, and perform data communication with the derived base station, thereby reducing the probability of degrading the connection to an optimal cell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If area blocks are made large to reduce the number of blocks, then the complexity of managing area blocks is reduced, but the precision of base station selection deteriorates
Solution Approach 1:
The patent divides the service area into multiple area blocks, where each area block is associated with specific base stations. This segmentation allows the terminal to efficiently search for optimal base stations by querying only relevant area blocks based on its current location, reducing management complexity while maintaining selection precision through location-based filtering.
Solution Approach 2:
The patent introduces area blocks as intermediary structures between the terminal and base stations. Area blocks serve as mediators that organize base station information in a location-based hierarchy, enabling the terminal to navigate and select base stations more efficiently without requiring complex global search algorithms.
2Measurement precision
If area blocks are made small to increase selection precision, then the accuracy of base station selection is improved, but the number of area blocks increases leading to higher complexity
Solution Approach 1:
The patent implements segmentation by dividing the service area into manageable area blocks, each containing specific base station information. This segmentation enables precise base station selection through location-based queries while keeping the overall system manageable by organizing data in a hierarchical structure that can be efficiently traversed.
Solution Approach 2:
The patent applies partial action by having the terminal query only the area blocks relevant to its current location rather than processing all area blocks. This selective querying approach maintains high selection precision for the active area while avoiding the complexity of managing and processing the entire set of area blocks.
3Reliability
If the terminal searches for optimal base stations using traditional methods, then the connection probability to small cells is maintained, but the time required for base station selection increases
Solution Approach 1:
The patent implements preliminary action by pre-organizing base station information into area blocks with location data before the terminal needs to make a selection. This pre-processing allows the terminal to quickly query relevant area blocks based on its current location, reducing selection time while maintaining connection probability to optimal small cells.
Solution Approach 2:
The patent employs feedback mechanisms where the terminal uses its current location information to feedback-select relevant area blocks for querying. This feedback loop enables the terminal to dynamically adjust its search based on real-time location data, reducing selection time while preserving the ability to connect to optimal base stations.

AI summary
A wireless terminal capable of communicating with multiple wireless base stations through a network in which multiple wireless communication methods are used in a mixed manner. A storage unit stores, as a communication history, at least location information for the wireless terminal and information pertaining to the wireless base station at the time of communication with each wireless base station. An acquisition unit acquires the location information for the wireless terminal. On the basis of the acquired location information for the wireless terminal and the communication history stored in the storage unit a derivation unit derives a connection base station from the multiple wireless base stations, as the wireless base station to be used in data communication. A communication unit performs data communication with the derived connection base station.
